Product Description

Extrusion screen pack changers double plate screen changer
GM-DSP series

In comparison with the double pistons continuous screen changer, the GM-DSP series double slide flat continuous screen changer allows a quicker screen change. This advantage is
Based on the optimized volume of filtering chamber, which minimized the
Duration of the venting procedure. The new sealing system allows the operation in extrusion lines with high pressures.
In masterbatch production process, consider about the change of color, we need to clean the extruder everytime when we need to change the color of the pellets, so it requires the chamber of the screen changer no any dead spots, and the raw material will not be residual in the dead spots.
The features of the chamber /flow channel of this kind of double slide flat continuous screen changer is no geometry dead spots.
So this kind screen changer now is widely used on the master batch extrusion line for melt filtration.

Extrusion screen pack changers double plate screen changer
The main body of the screen changer
Hydraulic unit with accumulator
Electrical controlling pack

Characteristics of GM-DSP series
Extrusion screen pack changers double plate screen changer
Two round removable breaker plates on each slide plate
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Equiped with air venting system
Fit for almost all kinds of polymers
It works well under the high pressure 400bar(40Mpa) not impact the high performance.
The filtration screen area covers from 100cm² To 980cm² , depending on the size, fit for output range from 100kg/h to 3700kg/h.

Tips for customers

 

How to choose a most suitable type of screen changer for your extrusion line ?

After the equipment supplier making a size recommendation and then you should perform your own analysis to confirm appropriate sizing. That way, you will have the advantage of independent analyses and, best of all, there is no additional cost.
Learn the difference between price and cost. Be sure to take into consideration all of the variables and look at all the factors to determine the real cost of ownership for the screen changer. Some of the hidden variables to consider may be:
？Product quality.
？Maintenance, time and cost of parts.
？Process downtime and cost.
？Life expectancy for the equipment and amortized cost of ownership.
？Cost and availability of filtration media.
？Pressure loss and effect on line output and product quality.
？Operator safety.
？Required operator intervention and labor cost.
If all of these and other factors are taken into consideration, you can choose the most suitable solution, and then you can expect a much better return on investment.
